Title: Power transmission/distribution line fault localization method and device
Inventor: TORIKAI TAKAYUKI
IPC: G01R31/08
Filed: 2022-03-29
Abstract: To localize a fault point generated in a power transmission/distribution line only by a surge detection time difference without using a surge propagation speed.SOLUTION: Assuming that respective points in an arbitrary section where a fault point of a transmission/distribution line subject to a fault point localization is interposed, are defined as fault points, storage means 4 makes time differences TB correspond to the respective points, the time differences of rising points of surge waveforms detected, with their interposed between the respective points, and stores them as a time difference group TBn. When a fault occurs, calculation means 9 calculates a time difference TA of voltages or rising points of surge waveforms measured at both ends of the arbitrary section. Comparison means 10 compares the time difference group TBn with the time difference TA calculated when the fault occurs, calculates, from the time difference group TBn, a time difference with a minimum error from the time difference TA, and localizes a point corresponding to the time difference as a fault point. A time difference of an unknown point is calculated by time difference interpolation processing so as to complement the time difference group TBn. Alternatively, it is also possible to correct a time difference representing abnormality in the time difference group TBn.SELECTED DRAWING: Figure 1
